Abstract
Certain aspects relate to a blended wing body aircraft with a fuel cell and methods of use. An exemplary aircraft includes a blended wing body, at least a propulsor mechanically affixed to the aircraft and configured to propel the aircraft, at least a first fuel store configured to store a first fuel, and at least a fuel cell configured to combine the first fuel with oxygen to produce electricity.
Claims18
A blended wing body aircraft with a fuel cell, the aircraft comprising:
- a blended wing body aircraft;
- at least a first fuel store located within a transitional portion of the blended wing body aircraft and configured to store a first fuel, wherein the at least a first fuel store comprises a fuel environment mitigation configured to regulate the temperature and pressure of the first fuel, wherein the fuel environment mitigation comprises an insulation, wherein the insulation comprises a vacuum chamber disposed between an inner wall of the at least a first fuel store and an outer wall of the at least a first fuel store, and a pressure vessel wherein the pressure vessel is further configured to control fuel pressure;
- at least a fuel cell configured to combine the first fuel with oxygen to produce electricity;
- at least a second fuel store located within the blended wing body aircraft and configured to store a second fuel wherein the at least a second fuel store comprises a second environment mitigation configured to regulate the temperature and pressure of the second fuel, wherein the second fuel environment mitigation comprises a second insulation, wherein the second insulation comprises a second vacuum chamber disposed between an inner wall of the at least a second fuel store and an outer wall of the at least a second fuel store, and a second pressure vessel wherein the second pressure vessel is further configured to control a second fuel pressure;
- an auxiliary power system operatively connected with the at least a fuel cell, wherein the at least a fuel cell is configured to power the auxiliary power system, wherein the auxiliary power system is configured to power an anti-ice system and a braking system while in flight;
- at least a propulsor mechanically affixed to an upper aft surface of the blended wing body aircraft and configured to propel the blended wing body aircraft;
- and
- at least a nacelle configured to encapsulate the at least a propulsor.

A method of use of a blended wing body aircraft with a fuel cell, the method comprising:
- storing a first fuel, using at least a first fuel store located within a transitional portion of a blended wing body of the blended wing body aircraft, wherein the at least a first fuel store comprises a fuel environment mitigation configured to regulate the temperature and pressure of the first fuel, wherein the fuel environment mitigation comprises an insulation, wherein the insulation comprises a vacuum chamber disposed between an inner wall of the at least a first fuel store and an outer wall of the at least a first fuel store, and a pressure vessel wherein the pressure vessel is further configured to control fuel pressure;
- combining the first fuel with oxygen to produce electricity, using at least a fuel cell;
- storing a second fuel, using at least a second fuel store located within the blended wing body, wherein the at least a second fuel store comprises a second environment mitigation configured to regulate the temperature of the second fuel, wherein the second fuel environment mitigation comprises a second insulation, wherein the second insulation comprises a second vacuum chamber disposed between an inner wall of the at least a second fuel store and an outer wall of the at least a second fuel store, and a second pressure vessel wherein the second pressure vessel is further configured to control a second fuel pressure;
- powering, using the at least a fuel cell, an auxiliary power system operatively connected with the at least a fuel cell, wherein the auxiliary power system is configured to power an anti-ice system and a braking system while in flight;
- and
- propelling the blended wing body aircraft, using at least a propulsor mechanically affixed to an upper aft surface the blended wing body aircraft, wherein the at least a propulsor is encapsulated by at least a nacelle.
